I have no doubt that OTN is a true mosaic where scenes from two different places were used, often for the same song, Calling Elvis is an excellent example, I showed this in an analysis I did, scenes with 1 microphone, scenes with 2 microphones, with an overdub right at the entrance, after Mark's first guitar note, when the whole band and the sound mass enter, Mark says something like, "yeah, Alright", (I don't remember if that's what he speaks) but, if you have Deezer, just open the CE from the OTN and put it at the point 0:58 seconds Mark shouting that scream, then listen to any of the CE versions from the 4 nights that were used to elaborate the OTN and you will notice that there is no such line, suggesting that this was an overdub.
In addition, as far as I remember now, only Your and Your Friend and Brother in Arms are the faxes that are basically 100% the same as those present in the Bootlegs, that is, there is no "tampering" of any kind. There are parts of guitars that are only contained in the OTN and are not present in any of the 4 recordings that were used to assemble the OTN, which luckily we have available for analysis, I already did that and I know that through this analysis it is possible to identify where it contains overdubs , it's not about being improbable, it's something factual, those who have doubts just have the patience and courage to do this analysis that I already did, I did it with pleasure, because I love to investigate these details, I did it and I prove it.
